GEORGE A. ORROK, OE BROOKLYN, NEW YORK, ASSIGNOR TO FUEL ECONOMY ANDENGINEERING COMPANY, OF NEIV JERSEY.

GAS-PRODUCER.

SPECIFICATION forming part of Letters Patent No. 675,359, dated May 28,1901.

. Application filed April 19, 1900 To all whom it may concern.-

Be it known that I, GEORGE A. ORROK, of Brooklyn, New York, haveinvented a certain new and useful Improvement in Gas-Prod ucers, ofwhich the following is a specification.

This invention relates to that class of apparatus designed. for theproduction of a combustible gas from air or air and steam forced througha mass of incandescent fuel, the socalled producer-gas. 1

The invention embodies an arrangement and relation of parts particularlydirected toward facilitating the ready Workin g of the apparatus toeffecting a preheating of the air or the air and steam before-passingthe same through theincandescent material'or a superheating of the same,or both, and various other features and combinations, all of which areset forth with the aid of the accompanyingdrawings in the followingspecification.

The novelty of the invention will be more particularly described in theclaims appended hereto.

In the drawings above'referred to, Figure 1 represents a centralverticalsection through a gas-producer embodying my invention, and Fig. 2 atransverse section thereof taken on the plane of the line 2 2.

Similar letters of reference designate corresponding parts in bothfigures.

A designates the body of the producer, preferably cylindrical in formand surrounded by an annular shell A. These two parts are of suchrelative diameters as to form an intermediate annular space or jacketthrough which the air or air and steam passes prior to its delivery tothe lower portion of the mass of incandescent fuel. In this chamber apreheating of the air or air and steam is effected. This preheatingspace is shown to extend from the top and above the body A to the bottomof the same, and at its bottom it delivers the air or air and steam intothe blast-chamber or twyer-box O through perforations c in the fixture0', connecting the body and the surrounding shell.

In the apparatus illustrated the blast chamber O is annular in form andsurrounds the downwardly-tapering conical bosh-plate D, perforated witha multiplicity of twyers d. These latter are preferably distributed sub-Serial No. 18,432. (No model.)

stantia'lly uniformly throughout the entire area of the bosh-plate forthe purpose of obtain- ,ing an equable and uniform air-current over theentire horizontal cross-sectional area of the overlying fuel.

While the chamber 0 has been defined as a blast-chamber or twyer-box inthat it is from thischamber the air or mixed air and steam issuesthrough the bosh-plate, it performs a further function. Lying adjacentto the zone of the fuel of the highest temperature, the contained air orair and steam is subjected to a further heating before its exit, whichmay be more properly defined as a superheating of the air or air andsteam, the blast-chamber or twyer-box constituting additionally,therefore, a superheating-chamber.

I 'Much difficulty is experienced in the practical operation of aproducer in freeing the material from clinker. If this is allowed toaccumulate to any considerable degree, its

presence interferes seriously with the satisfactory feed of thecarbonaceous material through the producer, besides exerting aninjurious effect upon the quality of the gas produced, &c. An absoluteessential to a satisfactory producer is some effective device for.

breaking up and removing the clinker. This result is attained with aminimum outlay of labor by embodying in the producer, in combinationwith the bosh, a positively-operating grate which shall be capable ofstirring up the mass of clinker and breaking the same up into piecessmall enough to be removed. I prefer a form of grate which shallaccomplish this result according to this mode, as distinguished from aform of grate in which the clinker is ground out, on account of the muchgreater labor involved in the use of a grinding-grate.

It is true if a bosh is used composed of bars that poke-bars may beinserted through the spaces between the former bars and the clinkerbroken up; but it is an object of this invention to obviate as much aspossible the necessity for the manual employment of pokebars bycombining with a bosh of the form described a grate Whose function andresults attain the same end by a much less expenditure of manual labor.This grate will-now be described.

Ice

Below the bosh-plate is arranged the grate D, which in the form hererepresented comprises a number of sets of bars 61', the bars in each setbeing substantially parallel to each other. As here shown, there arefour sets of these bars, and the various sets are combined with a deviceor devices to facilitate the shaking of the grate and the removal ofclinkers. The device represented may be adopted. Each bar d at its outerextremity is hinged to a lever E, secured to a rocking bar E, journaledin a suitable manner. Intermediate of its ends each bar (1 is supportedvertically in a manner to permit of its free lengthwise movement, aswell as allowing it to rock freely upon its support. For instance, itmay rest in a slot formed in the water-seal cylinder 6, projectingdownwardly from the bosh-plate. To the rocking bar E is secured an armE, which is fashioned to receive the end of a manually-operatedshaking-bar. The relation of the grate-bar, its support, and itsconnection are such as to cause the withdrawal of the bars from theirposition and the elevation of their inner ends when the rocking bar ismoved in its supports. This action will assist in freeing the grate ofany clinkers during the shaking down of the ashes. A center opening Fthrough the grate is left for the passage of the ashes. The ashesaccumulate in the water-seal tank G, being drawn out by hand from underthe cylindrical projection e, before referred to.

Any appropriate construction for supporting the apparatus may beadopted, that here shown comprising the supporting-columns H.

A common arrangement and construction of the parts are shown at theupper portion of the apparatus, as these features constitute no part ofmy present invention. These parts comprise a fire-brick or otherheat-resisting arch L, through which extend poke-holes Z, one or more innumber, closed by covers Z. The feeding-hopper is shown at M closed atthe top by the removable cover an and at the bottom during the chargingof the hopper by the spreading-cone m, held up in place by the weightedlever m H is the gas-outlet leading to the gas-main,

(not shown,) and H the inlet for air entering the preheating-chamber.

Having described myinvention, what I consider as new, and desire tosecure by Letters Patent, is

1. A gas-producer comprising in combination, a cylindrical body havingan annular, surrounding preheating-chamber,a lower conical bosh-plateprovided with openings or holes forming twyers, and a grate below thebosh-plate embodying means for raising the mass of clinker and breakingthe same up.

2. A gas-producer comprising in combination, a cylindrical body havingan annular, surrounding preheating -chamber, a blastchamber ortwyer-box, a lower conical boshplate provided with openings or holesforming twyers and constitutingone wall of the blastchamber ortwyer-box, and a grate below the Dosh-plate embodying means for raisingthe mass of clinker and breaking the same up.

3. A gas-producer comprising in combination, a cylindrical body havingan annular,

surrounding preheating-chamber extending above the body, a blast-chamberor twyerbox, a lower conical bosh-plate provided with openings or holesforming twyers, and a grate below the bosh-plate embodying means forraising the mass of clinker and breaking the same up.

4. A gas-prod ucer comprising in combination, a cylindrical body havingan annular, surrounding preheating-chamber extending above the body, ablast-chamber or twyerbox, a fixture between the said preheatingchamberand the blast chamber through which the air passes from the former tothe latter, a lower conical bosh-plate provided with openings or holesforming twyers, and a grate below the bosh-plate embodying means forraising the mass of clinker and breaking the same up.

In testimony whereof I have hereunto signed my name in the presence oftwo subscribing witnesses.
